We're Dick and Joanne- We have a Snowbird Legend fifth-wheel and a GMC 3500 dulley with the 8.1 L. and Allison trans 4.10 rear end. Most of our camping is in the winter at the Swain Ski area in New York where we are on the Ski Patrol. My 19th year on Patrol. We did take our first extended tour of Maine last summer in the camper. Great time. Looking forward to more adventures.
